Why is an anonymous currency important?
I've heard that side-chains make altcoins redundant?
It is up to any user to decide if anonymous currency will be off any use to him or not. Monero holders now speculate that there will be small part of crypocoin users that will prefer their wealth and their transactions to stay anonymous. I see that as a fact, speculation is how big will this niche be.
Potential users come to the FAQ to decide if anonymous currency will be of any use to her or others:
Bitcoin is a pseudonymous currency, where all transactions are public. If someone knows your Bitcoin address, they can learn your past transactions. Thus, Bitcoin is far less private than fiat, and unsatisfactory in many circumstances: anyone can potentially learn your past purchases or your Bitcoin wealth. While there are approaches to increase privacy with Bitcoin, these have limitations. Monero provides untraceable payments from the ground up, through the CryptoNote technology.
None alt coin that bringing something new will ever be redundant.
This is not true. Many coins offering "something new" fail. There are plans to implement Ring Sigs on side chains. The question is whether there is a true benefit in doing this (e.g. security), and whether the need to park BTC reduces anonymity substantially.
BTW, I'd suggest reordering the FAQ somewhat so more basic questions about the coin are at the top, rather than more technical installing/using questions. Ressources has one "s".
Thanks
